Is it possible to have hair particles [people] face towards a target
Use a Force Field:

Hair particles, even without using dynamics, follow the force fields:



In the Viewport do Add > Force Field (type "Force"). Place it where you need it to be. From the Physics properties panel, set the force to a negative value and leave the rest as it is.

The internal rotation of the base hair particle (humans) must be adjusted to make sure that the correct side points to the Force Field. In my case this is the mesh used:



Note that the "face" is looking towards negative Z, while the "head" is "up" in the direction of positive Y. The correct rotation must either be achieved in edit mode or obtained in object mode and then applied (CtrlA > Rotation)

You need neither the "Advanced" setting on Emission, nor the "Rotation" extra settings.
